Answer:
Rate of Change: 30 ???
Initial Value: 15 ???
Slope Intercept Form: y = 15x + 15 ???
(Please read explanation)
Explanation:
For rate of change use y2 - y1 / x2 - x1
So I believe there are points on (2, 40) and (6, 100)
Now we do 100 - 40 / 6 - 2 = 30
Initial value is what point is on the y axis. It's blurry, so my estimate is around 15. Check yourself though, because an estimate is an estamite!
For slope-intercept form use the formula y=mx+b
m is the slope, or rise/run, which in this graph I think is 60/4, or 15??
b is y-intercept, which is also the initial value, 15.
To be honest, I don't think my answers are accurate. Try using how I got my answers to check yours. Sorry this isn't the best help! Please comment
